We had to have our 12 year old water heater replaced due to a slow leak. Core Plumping was prompt, professional, fast and thorough with very high quality of work and parts. New water hear, expansion tank, and all new fittings. Very clean install. Will work with them in the future. read more

The water main had a leak. I called and they came out within a few hours and explained what needed repair. They started work late afternoon and put in place a line so there was water in the house overnight. The repair was done by the next day which was so appreciated. Communication was excellent throughout, professional and helpful. I would definitely use them again and recommend to family and friends. read more

Core plumbing came to do a flush of my tankless water heater and the service was excellent. The tech reviewed the tankless heater history and did a very good job of providing a complete check of it. Very pleased with the service call. read more

The initial service call was informative and helpful and the service requested was completed cleanly and completely. The next day was when the service was done and Josh did an excellent job. He was prompt, polite, and very complete in the services we needed and requested. Before the complete service was done, he checked everything that may be impacted and ensured everything worked. Will certainly use them again. read more

Kitchen faucet broke, we knew we would also likely need to replace the janky water heater we inherited when we purchased our house a few years ago. Grant came by, gave us an honest assessment and quote. My wife and I felt pretty good about their approach, so we added a house water filter too. Small job became a bigger job and they were able to scale up and keep the ball rolling. By the end of the day our old water heater was removed with a temp set up in its place. New water heater and filter were on-site. Day 2: Water heater (new tankless - requiring a new gas line) and kitchen faucet installed and running flawlessly. Day 3: Water filter installed and doing its magic. Core's plumbers are all professional and on-time. You'll receive text updates with the guys' names, photos, and ETA's the day of the work. They do good, complete work and clean everything up afterwards. All of this makes them unicorns in a post-pandemic world, from my experience. They back their work. (They even put up with my highly-reactive - thus barky - puppy very well.) They might not be the budget-friendliest solution, but you get what you pay for with plumbing in lovely San Diego. We'll continue to use CP if/when things come up and recommend them to friends without hesitation. read more

Updated review as we used them a 2nd time. They were prompt and always quick to respond and kept us up-to-date with any changes, etc. The pricing was about what was expected and were friendly and seemed knowledgeable. Thanks again! read more

we're repeat customers and just had another excellent experience. We upgraded our waters heaters with a water-softening system. Grant from Core put together an estimate, recommended cleaning and flushing the existing system, and sent Mike out the very next day to do the work. They alert you when they are on the way, are always on time, and I can reach them by text or phone immediately. Fabulous company. read more

We are a repeat customer and had our tankless water heater replaced. They were on time and did a great job.

Great customer service and very knowledgeable. Took care of so many of my random plumbing issues.

Timely and efficient service. Did a great job repairing my sink and getting the drain all back into place.

Kevin came to our house to performing some plumbing that was needed. He did a thorough inspection and was able to find not only what was asked, but some other critical plumbing related items in the house that needed to be replaced. he is very knowledgeable and explained the entire process/components thoroughly in a matter that we can understand. He was able to give us a quote right away, which we thought was very reasonable especially for someone of his expertise. He completed the work in a timely matter and with care. We feel extremely satisfied and will call him again in the future for any of our Plumbing needs. Core Plumbing is a company that you can trust to do the right thing with attention to detail and at a very reasonable cost. Highly recommend. read more

Core Plumbing - Working on water heater - Plumbing Near Me

We needed a seismic gas shutoff valve installed. Grant came by, evaluated our options, and gave us a free estimate. After he ordered the part, we were quickly able to schedule the install. Everything from approving the estimate, scheduling, tracking the technician, and final payment went very smoothly with their Housecall Pro service. Tony and his apprentice installed the valve. They did a great job and explained everything. After completion, they cleaned up everything. I can highly recommend this company and would hire them again for another job. read more

This is an edit to a previously posted review. I had some concerns about the price of the service I received, and the fact that the water supply to my toilet had been left disconnected. Within an hour of posting the review, Tim from Core Plumbing contacted me. He explained that the higher cost was due to water jetting the line, as opposed to just cabling it. I understand, and I did approve the work. Also, he apologized for them leaving the toilet supply disconnected, and he did compensate me for my time. All-in-all a good service. Would recommend. read more

The plumber was very knowledgeable and provided us with some options and associated costs. We were able to make a decision on how to proceed and he completed the work same day. We ended up replacing the toilet the builder originally installed (which was the incorrect size and faulty). I've been a customer for over 15 years and I trust Core Plumbing! read more

Josh was a very competent plumber for a complex job--and he was very nice too! I'll certainly call Core the next time I need a plumber.

Excellent experience! Core was knowledgeable, quick and efficient. They were responsive to my situation and had someone out and had my water pressure gauge regulator fixed in about 1:30 minutes . He walked me through what I needed to have done! They did their testing and was happy with the excellent work they provided. I would use them again! Especially if I needed something done quickly! Great communicators! Thanks Core read more

Core Plumbing - Plumbing Near Me

Core Plumbing helped me move my laundry machines. Everyone was really friendly and knowledgeable. I would definitely use them again for a big job I wanted to make sure was done right. Everything they did looks great. read more

Issues with my water heater not venting. Got multiple quotes, he comes in and also sees it's not venting (like I already knew and called him for). After trying to quote me many thousands more than last guy, he also tells me if I don't get it fixed right away he will call fire department and get my gas shut off after I declined his initial quotes for full replacement. I told him I can just turn off water heater, and no safety issue. He kept making threats to intimidate me into instant service and I declined. He then reported me to SDGE after I declined to cave into his threats. Would never work with tbis guy. Simply turning off heater until it's fixed is solution. Now he's trying to get my gas shut off so I can't heat my home or use the stove. What a complete joke this is. Other plumber quoted me $600 he comes in and tries to fleece me for $8000 worth of extra stuff I don't need. read more

I recently had my kitchen sink replaced by Core Plumbing, and I couldn't be happier with the results. Porter and David did an outstanding job; they expertly removed my old undermount sink and precision-cut and shaped the granite countertop to perfectly fit the new top-mount stainless steel sink. They also installed a new water filter system and left the entire workspace spotless. Their dedication and hard work were evident throughout the process. Additionally, the owner, Grant, was a pleasure to work with--he provided a fair estimate and took the time to clearly explain every step of the replacement. I highly recommend Core Plumbing, Porter, and David if you want your plumbing work done to perfection! read more

Awesome service and attention to detail and making sure the customer is satisfied! we use Core Plumbing and have for years!

The old guy seems disrespectful & angry. Shop around, lotsa plumbers to choose from in north county.

Our water heater went out so we were in a rush to get a plumber to our house. We called on Saturday afternoon, got an appointment for Monday morning, and the job was completed by Monday afternoon. So easy! read more

Core Plumbing did a great job on our whole house re-pipe. They were polite, courteous and professional. Took care of our belongings and protected the flooring and furniture. I've used them previously and will most likely use them in the future. read more

Always excellent service. I've been using Core for about four years now and they do high quality work. Communication is easy and they arrive at the job on time. read more

This is our third job with Core and just as the two times before, it was fast efficient done correctly and everyone was really nice. I didn't run a thorough comparison on price this time just because I was determined to go with core but pricing in the past has been competitive but not the cheapest. Worth every penny. read more

If you need help with a plumbing problem, you can't go wrong reaching out to Core Plumbing for help. We recently had to have our water service from the street to the house replaced, which of course meant digging a trench across the yard. I knew that the plumbing work would be top notch when I called Core, because we've had them handle a couple of other significant jobs that went really well. What I didn't expect, though, was what a great job Core would do minimizing the impact on the yard from the trench work. You can hardly tell a trench went through the yard just over a week ago! Many thanks to Grant, Joe, Josh, and David for a job really well done. If you need help with your plumbing and you're not sure who to turn to, give Core Plumbing a call . . . I know I'm glad I did. read more

I had water leakage issue. I post my request through Yelp, Core Plumbing responded in less than 30 minutes and the technician showed up my door less one hour later. Porter, the technician, checked my issue and identified the root cause of the leakage quickly. He explained in details about the few options I have, very professionally. Now I have a few approaches to resolve the issue. read more

Workmanship more than I expected. Friendly, courteous, and knowledgeable. Would use again without a doubt.

Upstairs shower drain clogged, CORE came out (quickly, to their credit) and quoted $680. Got it done with another plumbing company for $57 (another quote was for $180). $680 is unreasonable. read more

Friendly service, very efficient. They were great with communication and highlighting future areas of concerns. Would recommend their services to anyone needing plumbing done. read more

Joe, his colleague, and the GM came to our place to check for a possible leak, and we really appreciated how thorough they were throughout the inspection. They took the time to explain everything clearly, and their assessment made a lot of sense to us. We also felt comfortable with the quote we received. Overall, we had a very positive experience and would definitely reach out to them again if we need plumbing help in the future. Thank you! read more

Core Plumbing has a great combination of clear communication, reliability, expertise, technology enablement, and bedside manner. I wouldn't tell you they're the cheapest in town because you can probably find people willing to do hard jobs for less, but in a stressful situation like an SDG&E lockout due to a gas leak, it's worth hiring the most punctual, reliable, and effective people to do the job. Core delivered! Thanks to the team members who helped us out. read more

Showed up super fast same day to assess the issues. Would recommend For all your plumbing needs. Wore booties to keep the house clean. read more

These guys are awesome! A main water line was busted by a vehicle and took out water for so many people. This happened at 930 at night (no one got hurt thankfully). These guys got there asap in the morning and worked nonstop like 18+ hours until it was fixed. Two thumbs up read more

Responded very quickly to our phone call for help when we had water pouring down our driveway late on a Thursday evening. Gave us a temporary fix over the weekend so we had running water, and started work Tuesday morning to replace the main line to the house. Although this involved digging a trench down the middle of the driveway, they did a fantastic job, worked efficiently, and cleaned up well when they finished. Thank you Core Plumbing! read more
